You know there was a guy on rv.net forum that quit smoking by putting his cigarette money in a jar to save to buy a camper. That was one of the longest and most posted threads they have ever had over there.
After the better part of a year (I forget actually how long) he went out and bought a little used travel trailer (mid 20ft range) and had kicked his habit.
As I recall his screen name was "absofbeer"
